This feature, coupled with other characteristics of the system, suggest a close similarity between the Omani upwelling system and the Peruvian and California upwelling systems, where primary production (PP) is limited by iron. An intensification of upwelling, reported to have been caused by the decline in the winter/spring Eurasian snow cover since 1997, is not supported by in situ hydrographic and chlorophyll measurements as well as a reanalysis of ocean colour data extending to 2009. Iron limitation of PP may complicate simple relationship between upwelling and PP assumed by previous workers, and contribute to the anomalous offshore occurrence of the most severe oxygen (O₂) depletion in the region. Over the Indian shelf, affected by very shallow O₂-deficient zone, high PP is restricted to a thin, oxygenated surface layer probably due to unsuitability of the O₂-depleted environment for the growth of oxygenic photosynthesizers.
